An object in the present construction solve thc foundry problem to the joining of thin and thick sections. and to obviate the llitlicull'ics to the fitting ol' the bushing the result being secured by inserting a filler in the place of the portion which has heretofore been integrally formed in the eye of the bucket. In one of the forms of construction shown a still further advantage is secured in that the space within the eyc is n'iunr: opcn and accessible to the action of water in the: neat trmtmcnt which folhuvs the formation of manganese st cl (listings In order to cnublc those skill'ul in the art to fully mulcrstuml J incu cution is tlirciihtctl to the diuwm part of this up nit-:1 numhcrs rcpri Figure 1 u scum provcl huclcct, F: vicar throughthe i Pun-.1; :11? 3- ct ci'instrucictl ntion.

Thc buckets are cast in a position 90 deggtrccs removed from that indicated in Fig, l, lhut is. with the eye 15 at the top. at which point a riser is located the pouring gate being at one sitlc and the nctul being supplied near the lower portion oi thc casting when in the position indicated.

In a device of the class described, buckets of alloy steel having two front eyes and one rear eye, the rear eye of one bucket being adapted to be inserted between the front eyes of the succeeding bucket, said rear eye being provided with a length-wise semi-cylindrical cavity and a lengthwise substantially wedge-shaped cavity opposite thereto, a separate bushing fitted to said Wedge-shaped cavity with the longitudinal edges thereof extending into said semi-cylindrical cavity, the face of each lying in a plane with the axial center of the eye, and means for holding said separate wedgeshaped bushing in said cavity, substantially as described.
